The pH of a solution is a measure of its acidity or alkalinity. The pH scale ranges from 0 to 14, with 7 being neutral. Solutions with a pH less than 7 are acidic, while solutions with a pH greater than 7 are alkaline.The [OH-] concentration in a solution is inversely proportional to the pH. This means that as the pH increases, the [OH-] concentration decreases.In this question, we are given that the pH of a specific household cleaner is approximately 11.0 and the pH of an ammonia solution is approximately 8.0. We want to know how many times greater the [OH-] concentration is in the household cleaner than in the ammonia solution.To answer this question, we can use the following formula:```[OH-] = 10^-pH```Plugging in the pH values for the household cleaner and the ammonia solution, we get:```[OH-] in household cleaner = 10^-11.0 = 1.0 x 10^-11 M[OH-] in ammonia solution = 10^-8.0 = 1.0 x 10^-8 M```To find how many times greater the [OH-] concentration is in the household cleaner than in the ammonia solution, we can divide the [OH-] concentration in the household cleaner by the [OH-] concentration in the ammonia solution:```[OH-] in household cleaner / [OH-] in ammonia solution = (1.0 x 10^-11 M) / (1.0 x 10^-8 M) = 1.0 x 10^-3```This means that the [OH-] concentration in the household cleaner is 1000 times greater than the [OH-] concentration in the ammonia solution.Therefore, the correct answer is C) 1000.

The PH of a Specific Household Cleaner Is Approximately 11
